Part is fine but not sure if it was dented when shipped or got dented on the way to us. But it wasn't in a box so it was dented. Got 2 parts both not in box and both dented.

I replaced the OEM header/cat about three months ago. It resolved the 'check engine' light I had. More importantly, I haven't seen a decrease in power or fuel efficiency at all. This was a concern initially because the design of the Walker header doesn't appear to allow exhaust gases to move as smoothly. Great product overall.
